This morning I woke up, unplugged the charge cable, noticed it was powered off, powered it on. Appeared to be booting up normally. A few minutes later I noticed it was off again.
Then it wouldn't turn on. Tried removing battery for 5 minutes (while unplugged of course), no luck.
Trying to power it on:
- On battery: No response.
- On USB power with battery installed: Battery charging indicator shows on screen for a couple seconds when I try to power it on.
- On USB power with battery removed: Backlight flashes on and off for a couple seconds at a time.
It wouldn't boot to recovery either.
Tried a battery from a spare Venture, it booted right up with that battery while plugged in. Tried bad battery in spare Venture, that one booted when plugged in. Let spare Venture charge the battery all day, works fine on that battery.
So, FYI, if your Venture has symptoms like this, it may just be battery-related.
However, mobile data doesn't work. I have a full 6-bar signal (I can see the tower through my window from where I'm sitting). Usually I have a good 3G connection here. Also tried on the highway and at work...no data connection.
How do I even begin troubleshooting no mobile data connectivity?
